Digital vs. Analog cd-r recording/burning

[funkydrummer]

Um... Is it phisically possible to have an analogue CD? Don't all CD's record with 1's and 0's (aka digital)?

Digital information is written to the disc by burning (forming) pits in the recording layer. The energy of the laser beam - in the range 4 to 11 mW - causes limited heating of the substrate and recording layer to approximately 250 C. At this temperature the recording layer melts, reducing its volume, while the substrate expands into the space that becomes available. By constant switching between writing and reading power, a pit pattern corresponding to that of a conventional CD is produced.

IIRC, the only difference between audio cdr and data cdr is that the audio one has a bit identifying it as such which may be required by some hardware players. Its an old idea so no one really uses it anymore but for max compatabilty, use the audio one (there is no difference in quality)

I have one of those Philips. If I want to make a copy of one of my own discs I just run it from a cd player through my digital mixer then burn it to a disc in the Philips.

Sorry, I meant "anything" in terms of the discs you can use. You don't need the audio discs.

"...the reason Audio Disks cost more is because a portion of the price goes to the music industry...

More importantly, a portion of the price goes to songwriters who have publishing companies.
